Pachysentis is a genus in Acanthocephala (thorny-headed or spiny-headed worms) that parasitize primates and carnivorans. The eleven species are distributed across Africa, the Middle East, and the Americas. Pachysentis species attach themselves to the inner lining of the gastrointestinal tract of their hosts using their hook-covered proboscis. Their life cycle includes an egg stage found in host feces, a cystacanth (larval) stage in an intermediate host which is usually an insect, and an adult stage where cystacanths mature in the intestines of the host. This genus appears identical to the clos

Heptamegacanthus is a genus of acanthocephalans (thorny-headed or spiny-headed parasitic worms) containing a single species, Heptamegacanthus niekerki, that is a parasite of the endangered giant golden mole. It is found only in isolated forests in the Transkei and near East London, both in South Africa. The worms are about 4 mm long and 2 mm wide with minimal sexual dimorphism. An individual's body consists of a short, wide trunk and a tubular feeding and sucking organ called the proboscis which is covered with hooks. The hooks are used to pierce and hold the rectal wall of its host.

However, research on the morphology of the group and their use of hosts has concluded that Profilicollis and Polymorphus should be regarded as distinct genera, and species previously described as Polymorphus altmani are now referred to as Profilicollis altmani in taxonomic and biological literature. Profilicollis parasites infect decapod crustaceans, usually shore crabs, as intermediate ho
